I myself would prefer the game without the non-historical units BUT i understand that CA needed to appeal to the wider audience to bring in the cash to keep making this series of games which we ALL love.
The bone that they threw to us who want a more realistic game is the fact that the game can be modded so easily.Just look at Medieval which was fairly accurate compared to Rome.They read this site and see that we complain about a lot of issues and mod them to suit ourselves anyway.I have no doubt that the likes of Wes,BKB andthe LOrdz will make many great mods which we will all enjoy.
Hurrah for CA.Without you we wouldn't even have this opportunity to voice our complaints.
